The cutting of " Bohai Sea two " drilling platforms alloy spud leg.1988, the cutting cartridge suitable for oil pipe cutting was succeeded in developing, and was cut
Principle is equally the penetration effect with energy-gathering jetting.In addition, Yan Shilong et al. to jet cutter underwater demolition cutting steel plate into
Experimental study is gone, using most descending square law to analyze the factor for influencing depth of cut, and proposing should be according to cutting
It is required that from process safety, cutting effect and economic benefit etc. complex optimum cutter parameter.Li Xinhui etc. is to ring-type
The submerged performance of cavity blasting cutter is studied, and carried out bursting property test under water, it was demonstrated that poly- using V-type
Energy cavity liner can achieve the purpose that cutting or damaged underwater flexible chain.
Although having much for the research of linear cavity effect cutter, most of experiments are all to carry out in air medium
, underwater demolition technical research is relatively weak, is concentrated mainly on the fields such as numerical simulation, test and engineer application, underwater demolition
Mode is still based on underwater contact demolition and non-contact demolition.Since aqueous medium influences very big, underwater demolition to melt injection
Test is not only difficult to carry out but also success rate is very low, more and more the problem of being difficult to testing and verification start by computer means into
Row numerical simulation studies water-bed shock wave wave propagation, fluid structurecoupling problem etc. to carry out cavity liner and explosive waterproof measure
While guarantee penetration effect.
